Eruf: porsche carrera with electric drive

Pfaffenhausen, 13. October 2008 – exact numbers are difficult to get, but that powerful lithium-ion batteries can not be cheap, is obvious. So in the tesla roadster over 6000 battery cells are installed, for that you have to laugh at locker 1000 laptops. In may 2007, the marketing chief of tesla in the los angeles times at least elicit the exercise that the price "north of 20.000 $ "is how far in the north, he did not say. But that’s exactly this prize problem makes sports car attractive as an experimental field for electric drives and the expensive energy storage, because there is a few hurts the customer. That may also have thought of the allgauer porsche tuner reputation, which actually wants to bring a porsche 911 with electric drive on the market.

204 elektro-ps in the rear

The contributed to the project gave according to the company information holders alois ruf himself. The busy bayer has some hydroelectric power plants, with which he feeds 35 million kilowatt hours per year into the observational power grid. So why do not drive a sporty car with this clean electricity? As the basis served a porsche 911 carrera. The result acts practically as a conventionally fired pre-facelift-997. Under the sheet, however, the six-cylinder boxer engine had to soften a clearly cleaner technique: a burstless three-phase ac motor sits behind the rear axle differential and provides 150 kw power and 650 newton meter torque for propulsion.

About 300 kilometers range

The electricity for the electric machine is stored in 96 lithium-ion cells derived from the manufacturer axeon. Each of them weighs 5.6 kg, so the whole battery pack makes more than half a ton of weight, which wants to be distributed in the vehicle in the vehicle. A coarse part of the cells is installed in the vehicle rear of the engine, some batteries, however, have squeezed the call developers in the trunk of the elf and thus in front of the front axle, otherwise the weight distribution was probably still tail-heavy than it is the case anyway. In total, the batteries should range from 250 to 320 kilometers driving route. At a treasured life of 3000 charging cycles, the cells had to be after 750.000 to 960.000 kilometers exchanged.
